WRAPPING-MACHINE.

Specification of Letters Patent.

Patent-ed J an. 13, 1914.

Application filed February 17, 1913. Serial No. 748,940.

To all whom it may concern:

Be it known that we. HILARIO on Escon- ALES, a citizen of the Island ofPorto Rico, and F RANCIS P. AMPUDIA, a citizen of Spain, both residentsof the city of New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements inrapping-Machines, of which the following is a specification.

This invention relates to machines in which an article and wrapper arepassed through folding devices'whereby the wrapper is folded upon thearticle.

The object of the invention is to provide a means by which this can bedone in a simple and eliicicnt manner.

The invention consists of two adjacent heels and means for imparting anintermittent rotary movement thereto. Said wvheels are provided with aseries of receptacles adapted to receive partially wrapped articles, andare provided with plungers adapted for reciprocating movement in thereceptacles on diametrically thereof.

Continuously revolving rollers cause paper to be fed between a pair ofscissors, into guides for a wrapper. A movable member of the scissorsis, connected to said means for imparting an intermittent rotarymovement to said wheels, in such a manner that the paper is cut by thescissors during the movement of said'wheels.

The machine is provided with a reciprocating plunger by which an articleand wrapper are forced through stationary folders, and into one of saidreceptacles on one of said wheels, whereby the plunger in saidreceptacle is forced into the receptacle on the diametrically oppositeside of said wheel, causing a partially wrapped article in the lastnamed receptacle to be moved into a reccptacle of the second wheel,whereby the plunger in said receptacle of the second wheel is forcedinto the receptacle on the diametrically opposite side thereof wherebythe partially wrapped article therein is forced out.

In the accompanying drawings Figure 1 is a sectional side elevation ofthe machine. Figs. 2 to 8, inclusive, are perspective views showingdifferent stages of folding of the wrapper upon the article. Fig. 9 is aplan view of the machine. Fig. 10 is a detail view. showing the meansfor imparting an intermittent rotary movement to said Wheels.

Opposite sides Figs. 11 and 12 are detail views showing the constructionof the scissors. Fig. 13 is a view of the cam for actuating thescissors. Fig. let is a side view of one. of said wheels. Flg. 15 is asect-ion on the line A, B, ofFig.

1 1. Figs. 16 and 17 are detail views showing certain movable parts ofsaid receptacles. Figs. 18, 19 and 20 are detail views of said plungershaving reciprocating movement within said wheels.

A horizontal driving shaft 1 is journaled in suitable hearings on theframe 2 of the machine. A lever 3 is centrally pivoted at 1 on the frame2. One end of lever 3 is provided with a roller which engages a cam 5 onshaft 1'. The other end of lever 3 is connected by a link 6 to a plunger7- which is adapted for horizontal reciprocating movement in guides 8.

Secured to shaft 1 is a bevel gear wheel 9 in mesh with a bevel gearwheel 10 which is secured to the lower endof a vertical shaft 11. To theupper end of shaft 11 is secured a bevel gear wheel 12 which is in meshwith a bevel gear wheel 13 secured to a shaft 14. Secured to shaft 14:is a roller 15 and a gear wheel 16. Gear wheel 16 is in mesh with a gearwheel 17 which is secured to a-shaft 18. i-ilso secured to shaft 18 is aroller 19, the shaft 18 being journaled in movable bearings 20 which arepressed by a spring 21 so that the roller 19 will maintain a yieldingpressure against the paper 22 which is pressed between the rollers 16and 19. Said rollers serve to feed the paper downward into the guides23.

Secured to vertical shaft disk 24, having 25. As shown in Fig. 10;during part of the rotation of shaft 1-1, pin .25 engages one of aseriesofsix slots 26 formed in a horizontal disk 27. Disk 27 is securedto a vertical shaft 28. During the engagement of in 25 with any one ofthe slots 26; the disk 27 and therefore the shaft 28 will move one-sixthof a revolution. During the time pin 25 is out of engagement with theslots 26, a vertically extending concentric projection 29 on disk 24will ride against a concave surface 30 formed on the edge of disk 27,which willcause the disk 27 and shaft- 28 to be held stationary duringthe time pin 11 is a horizontal 25 is out of engagement with the slots26.

Secured to vertical shaft 28 a bevel gear wheel 31 which is in mesh witha bevel gear wheel 32 on a horizontal shaft 33. It

a vertically extending pin into the receptacles 49.

will be evident that the intermittent movements imparted to verticalshaft 28, as above described, will be transmitted to the horizontalshaft 33, by means of the gears 31 and 32. Secured-to horizontal shaft33 is a wheel 34 having a cam groove A lever 36 is centrally pivoted at37 on the frame 2. One end of the lever 36 is provided with a roller 38which engages the cam groove of wheel 34. The other end of lever 36 isconnected by a link 39 to the movable blade 40 of a pair of scissorswhich are mounted upon a vertical rod 41. The stationary blade 42 issecured to rod 41 and the movable blade 40, pivoted upon the rod, isheld against the stationary blade by means of the spring 43. The camgroove 35 is so shaped that its action upon the above describedconnection to the scissors is such that the movable blade remainsstationary during the time the shaft 33 is stationary. When the shaft 33is moved, the cam 35 will cause movement of the blade 40, causing thepaper blank 44 to be out free from the paper 22, which is fed'from thesupply roll indicated in Fig. 1.

An article 45 to be wrapped is placed between the plunger 7 and thewrapper blank 44. Forward movement of the plunger will force the articleand the wrapper between the upper plate 46 and the lower plate 47 andbetween the two side folders 48, causing! the wrapper to be folded uponthe article in the manner'shown in F 2. The forward movement of plunger7 is sufficient to force the article and partially folded wrapw; perinto one of a series of six receptacles 49 which are formed in theperiphery of a wheel 50. The receptacles 49 are each provided withmovable walls 51 which are pressed by a spring 52. so that the wallsmaintain a yielding pressure upon the wrapper of an article. The walls51 are provided with inward turned edges 53 which take against flangesthus serving to limit the movement of the Walls by means of the springs52. The outer edges of the walls 51 are inclined to form guides for thepartially wrapped articles as they are forced The partially wrappedarticle as it is forced into a receptaclc, pushes a plunger out thereofand into the receptacle diametrically opposite. The whcel 50'is providedwith three plunger-s I One of said plungers has a recess 57 on each sideof a central bar 58, as shown in Fig. 1.9. Two of the plungers areformed, as shown in F ig: 20, with a deep reccss 59 on one side and abar 60 on the other side. The bar 60 of one of these plungers is adaptedto fit in one of the recesses 57, and the bar 60 of the other plunger isadapted to fit in the other recess 57. The wheel 50 is formed of twodisks 61, each having grooves 62 adapted to receive the plungersassembled as shown in Figs. 14,

15 and 18. The two disks 61 are fastened together by means of the screws63. The disks 61 forming the wheel 50 are provided with extensionsforming the shaft 33.

It will be evident that the previously de scribed intermittent movementsimparted to shaft 33 will also be imparted to wheel 50, and also toanother similarly constructed wheel 64 on a shaft 65, which is driven bychain wheels 66 and chain 67 from shaft 33.

Two of the one-sixth movements of wheel 50 will cause the partiallywrapped article shown in Fig.2 to be moved to the position shown in Fig.3. Vhen in this position, a paste wheel 63 supplying paste from areceptacle (39 is moved downward, causing aste to be applied to thewrapper as is .hown in Fig. 1. is secured to a rod 70 which hasvertically reciprocating movements in a guide 71. The lower end of rod70 is connected by a link 7 2 to one end of a lever 78 which is pivotedat 74 to the frame '2. The other end of lever 73 is provided with aroller 75 which engages a cam 76 on shaft 1. by which it is actuated. v

One-sixth movement of the wheel 50 will cause the partially wrappedarticle shown in Fig. 3 to be moved to the position shown in Fig. 4.During this movement of wheel 50, the wrapper fiap 77 will take againstthe stationary folder 78, whereby the flap will be folded against thearticle. in the manner shown in Fig. 4. It will be evident that as thisarticle and wrapper fills this receptacle 49, the plunger 56 will fillthe res ccptacle 49 diametrically opposite. Then as the plunger 56 ispushed out in the manner previously described. this partially wrappedarticle will be forced from the receptacle 49 which it occupies, andinto one of the six receptacles 79 of wheel 64. When this occurs, theside portions 80 of the upturned flap 77 shown in Fig. 4 will takeagainst two stationary side folders 81. and at the same time. theportion of fiap 77 projecting above the article will take against a wall1 of the receptacle 79. causing the flap 77 and the side portions 80thereof to assume theposition shown in Fig. 5. It will'be evident thatthe paste 82 on flap 77 will cause the fiap to adhere to the wrapper 44previously folded upon the article.

When wheel .64 has 'ma de a half revolution, the partially wrappedarticle shown in Fig, 5 will be turned bottom side up, as is shown inFig. 6. Then as another-partially wrapped article is forced into thereccptaclc'79 diametrically opposite, a planger 56 of wheel 64 willthereby be forced into the first named receptacle 79, causing thepartially wrapped article contained therein to be forced out and betweenl upper and lower plates 82. The upper plate 82 is provided with twodownwardly probetween the adjacent wheels, whereby said wrapper isfolded upon the partially wrapped article, said paste applied to saidwrapper serving to hold the wrapper in place; and said movement of saidwrapped article in said receptacle of the second wheel causing theplunger in said receptacle of the second wheel to be forced into thereceptacle on the diam'etricall y opposite side thereof, whereby thepartially wrapped article therein is forced out and between said secondstationary folders, thereby causing remaining flaps to be folded uponthe wrapped article. p

4:. A wrapping machine comprising two adjacent; intermittently rotatingwheels, each wheel having a series of receptacles adapted to receivepartially wrapped articles and eaclrwheel having plunger-s adapted forre ciprocating l'norcment in the receptacles on diametrically oppositesides thereof; a pair of stationary. side folders between said adjacentwhcels, stationary folders on the diametrically oppesite side of one ofsaid wheels and second stationary folders on the .diametrically oppositeside of the other article to be forced into a receptacle of the firstnamed wheel, whereby the plunger in 1 said receptacle is forced into thefirst named receptacle whereby the partially wrapped article therein isforced out and into a receptacle of the second wheel, said pair ofstationary side folders between said adjacent Wheels during movement ofthe article taking against said wrapper, thereby causing side flaps tobe folded upon the partially wrapped article, and said, receptacle inthe second wheel having awall which during movement of the article,takes against said wrapper resting between the adjacent wheels, wherebysaid wrapper is folded upon the partially wrapped article; and, saidmovement of said wrapped article in said receptacle of the second wheelcausing the plunger in said receptacle of the second wheel to be forcedinto the receptacle on the diametrically opposite side thereof, wherebythe partially wrapped article therein is forced out and between saidsecond stationary folders, thereby causing remaining flaps to be foldedupon the Wrapped article.
